This is the ASK OOK modulated RF signal receiver module, it can directly replaced with classic rf link modules like this one.

Chip Features:

• Frequency range: 300MHz-440MHz
• High receiving sensitivity (2kbps, BER 10E-2)
  • -113 dBm @ 315MHz
  • -113 dBm @ 433.92MHz
• Low power consumption
  • 5.0mA/3.3V @ 315MHz
  • 5.0mA/3.3V @ 433.92MHz
  • 0.01uA/3.3V @ Shut Down Mode
• Low startup time: 3 ms
• Data rate: ≤ 10kbps
• Wide working voltage: DC 2.0V~ 5.5V
• Built-in image suppression, good anti-interference performance
• Receiving bandwidth: ±300KHz
• High ESD protection standard: ±8KV HBM
• Stand-alone operation without external MCU control
• No need for register configuration

Board Features:

• Pin Definitions: VCC 2.0–5.5V, ground and Data_OUT
• On board black spring antenna
• Board dimension 12.5 x 22 mm

Arduino can use radiohead ASK library and sketches.
